Heretofore such machines have been constructul for inserting the pointsinto the sash I hypressure. This mcthodisohjeetionahle; (or the reason ta u s a c amp ng o ng-el theemachine to the sash to resistgthe reactionof the pressure against the point necessaryfor its --insert ion, thusrendering the op-- era-tron eomprrnti-selyslow; a 1

plriectofmy'invention" is to preside a glazier -pointsetter which willdrive the-points without the necessitypf clampingthen achine' to thesash, and which will dothisaccurately m direction and depth and in closecontact with the face of the glass, and which will be readily adj-nstabie in the'i'orc'e of its blow, "according tothe-varying hardnessof the wood of j the sash. p The invention consists .in a striker mov'edbackward by the action-of a leverand forward 30 by the reaction .ofaspring.

It also consists in the connection, with-said striker, of adriving-plate, said plate also forming an opening and closing bottom tothe recep'tacle containing the points to be driven.

It also consists in an adjustable latchg-hy which the forceof the blowdriving the point may be regulated.
